Abstract

L'invention concerne un procédé pour chauffer une charge métallique (31) introduite en continu dans un four de fusion (30) par l'intermédiaire d'une deuxième section de chauffage horizontale (34) à travers laquelle passent les fumées chaudes collectées dans ledit four (30), lesdites fumées exerçant une phase de chauffage de ladite charge (31), caractérisé en ce que, juste avant de pénétrer dans ladite deuxième section de chauffage (34), la charge (31) est soumise à une phase de préchauffage par des moyens de chauffage différents des fumées collectées dans le four de fusion (30). Dans une installation pour la mise en uvre dudit procédé, lesdits moyens de chauffage différents sont envisagés à l'intérieur d'une première section de préchauffage (33) qui est fonctionnellement reliée à ladite deuxième section de chauffage (34) par une section intermédiaire d'évacuation des fumées (35), les fumées provenant desdites sections (33) et (34) étant transportées jusqu'à ladite section. Lesdites sections (33, 34) ont de préférence une configuration en tunnel.
